Trickle bed reactor

Abstract

The present invention relates to the field of fixed bed reactors, and discloses a trickle bed reactor, which comprises a reactor shell (10) and a plurality of bed layers (11) used for loading catalysts and arranged in the reactor shell, wherein the reactor shell has a material inlet (100) for feeding a raw material, a material outlet (101) for discharging a product, and a material discharge port (102) for discharging the catalyst, the bed layers are arranged along the height direction of the reactor shell, the trickle bed reactor further comprises a material discharge pipe (12) for the passingthrough of the catalyst, the material discharge pipe comprises a communication pipe section (120) and an extending pipe section (121) connected to the lower end of the communication pipe section andextending downward, and both ends of the communication pipe section respectively extend into the bottom portion of the upper bed layer and the top portion of the lower bed layer of the two adjacent bed layers. With the trickle bed reactor of the present invention, the backmixing rate of the catalysts in each bed layer can be reduced, and the backmixing phenomenon of the catalyst can be reduced.

Description

technical field [0001] The invention relates to a fixed bed reactor, in particular to a trickle bed reactor. Background technique [0002] Reactor is a kind of equipment to realize the reaction process, which is widely used in chemical industry, oil refining, metallurgy and other fields. The reactor is used to realize liquid-phase single-phase reaction process and multi-phase reaction process such as liquid-liquid, gas-liquid, liquid-solid, gas-liquid-solid, etc. Commonly used reactors include tubular reactors, tank reactors, bubbling reactors (also known as bubbling stirred tanks), stirred tank slurry reactors, tower reactors, and jet reactors. In addition, it also includes reactors with a bed of solid particles (also known as packed bed reactors), which are filled with solid catalysts or solid reactants, and when gases and / or liquids pass through fixed or moving solid particle beds to achieve multiple Phase reaction process, including fixed bed reactor, fluidized bed rea...

AI Technical Summary

Problems solved by technology

In the process of reverse unloading the catalyst, the catalyst is more broken, and the whole process will cause more catalyst loss; and it takes a long time, the labor intensity is high, and the working environment is harsh. Due to the long time consumption and high labor intensity, the production is greatly improved. cost
